Building new applications with + -D_FILE_OFFSET_BITS=32 will no longer be supported. The off64_t type and + the 64-bit function aliases (such as fstat64) will remain available under + the appropriate feature test macros. In preparation, libraries should + stop using off_t in public header files, and use off64_t (or a fixed-width + type such as int64_t or uint64_t) instead. + Changes to build and runtime requirements: * Python 3.4 or later is required to build the GNU C Library.
